High Capacity Granite Crushing System for 300 TPH

Project Description

A building materials enterprise in Qingdao, Shandong Province engaged in granite crushing. Introduced by a friend, it visited our factory for equipment inspection in 2021, and meanwhile checked the equipment operation in nearby areas such as Linyi and Weifang. Struck by the excellent particle shape of finished products and low wear of wearing parts, the enterprise selected the DLKPC Double-Cavity Hard Rock Crusher for granite processing.

Project Overview

Processing Material: Granite

Capacity: 500 TPH

Project Requirements: 05, 12, 13, 24 and other specifications of sand and gravel aggregates

Zhongyu Dingli 300 TPH High Capacity Granite Crushing System: Efficient Hard Rock Crushing Solution

As a high-efficiency turnkey crushing solution exclusively engineered for granite processing, Zhongyu Dingli’s 300 TPH High Capacity Granite Crushing System is tailored to solve the core industry pain points of granite crushing—extreme equipment wear (due to granite’s Mohs hardness 7 and high silica content), unstable large-capacity output, poor finished aggregate particle shape, and high operational costs. Integrating advanced Crushing Equipment, heavy-duty Stone Crusher, precision Vibrating Screen, optional Sand Maker, and Mobile Crusher modules, this complete system realizes a closed-loop process from granite raw material feeding, multi-stage laminated crushing, precision screening, to optional sand making & shaping. Backed by Zhongyu Dingli’s 30+ years of expertise in Crushing Equipment manufacturing and proven by numerous successful 300 TPH granite crushing projects worldwide, it maintains stable 300 TPH output, producing high-quality cubic aggregates—ideal for granite quarries, aggregate plants, highway, bridge, and large-scale infrastructure projects globally.

Core Advantages: 300 TPH High Capacity & Granite-Specific Optimization

1. Granite-Specific Design, Conquering High-Wear Challenges

Targeting granite’s high hardness (Mohs 7) and high silica content—a major cause of rapid equipment wear in crushing operations [7]—the system adopts a scientific two-stage crushing process: "Primary Jaw Crushing → Secondary Cone Crushing" [3][5], which effectively avoids over-crushing and reduces wear. The core Stone Crusher includes 1 set of PEW860 heavy-duty jaw crusher (primary crushing) and 1 set of HPT300 hydraulic cone crusher (secondary fine crushing) [1], equipped with Zhongyu Dingli’s proprietary NM500 wear-resistant linings and reinforced rotors. This exclusive design extends wear part service life by 2.5 times compared to ordinary Crushing Equipment, solving the industry’s key pain point of frequent wear in granite crushing [7]. For projects requiring manufactured sand, optional Sand Maker (vertical shaft impact crusher) can be integrated to process crushed granite into high-quality sand, maximizing resource utilization.

2. 300 TPH Stable Capacity, Guaranteed by Scientific Configuration

Precisely optimized to achieve 300 TPH (Tons Per Hour) high capacity, the system maintains stable output with a fluctuation range of ≤3%, supporting 24/7 continuous high-intensity operation—critical for large-scale granite processing projects. It is equipped with 1 set of large-capacity vibrating feeder (400-500 TPH capacity) to ensure uniform material supply to the Stone Crusher, avoiding equipment overload [5]. The system also includes 2 sets of 3-layer heavy-duty Vibrating Screen (200-250 TPH per unit) for multi-stage precision grading, separating aggregates of different specifications (0-5mm, 5-10mm, 10-20mm) [1][5]. The closed-loop design (unqualified materials returned to the Stone Crusher or optional Sand Maker for reprocessing) avoids material waste and ensures stable 300 TPH capacity output, with a comprehensive power consumption of only 2.3-2.8 kWh per ton—lower than the industry average by 12%.

3. Full-Process Integration, Seamless Linkage of All Core Modules

The complete system forms a highly integrated Crushing Equipment solution, with seamless linkage betweenStone Crusher, Vibrating Screen, optional Sand Maker, and Mobile Crusher. The optimized process flow is tailored exclusively for granite: Raw Granite Feeding → Primary Crushing (Jaw Stone Crusher) → Secondary Fine Crushing (Cone Stone Crusher) → Precision Screening (Vibrating Screen) → Optional Sand Making (Sand Maker) → Finished Aggregate/Sand Output [5]. The Vibrating Screen ensures precise grading, with qualified fine materials conveyed to the optional Sand Maker for deep processing, and oversized materials returned to the Stone Crusher for re-crushing—improving overall system efficiency by 30%. For projects with complex terrain or temporary operation needs, optional Mobile Crusher (crawler/tire type) can be integrated to eliminate long-distance material transportation costs and realize on-site flexible crushing and screening [3].

4. Environmental Protection & Intelligent Control, Complying with Global Standards

Adhering to the global "green mining" concept, the system is equipped with pulse dust collectors and fully enclosed Crushing Equipment, Stone Crusher, and Vibrating Screen, achieving dust collection efficiency ≥99% and dust emission <20mg/m³—complying with global environmental protection standards. The optional circulating water system (water reuse rate ≥85%) is configured for optional sand washing, reducing water consumption by 30% compared to traditional systems and avoiding environmental pollution caused by wastewater discharge [5]. Equipped with PLC + touch screen intelligent control system, it supports one-key start/stop, real-time monitoring of equipment load, production capacity, and wear status, and fault self-diagnosis—reducing manual operation intensity by 50% and ensuring safe, stable, and intelligent operation [7].

5. Durable Structure & Low Operational Costs, Maximizing Investment Returns

Built for long-term high-intensity granite processing, all core equipment adopts a modular design with high-strength steel frames and sealed structures—effectively isolating dust, water, and impurities, and reducing equipment failure rate by 40%. The Stone Crusher and optional Sand Maker use wear-resistant parts made of high-manganese steel and alloy steel, which are easy to replace and have low maintenance costs [7]. The optimized process design reduces material loss by 5%, and the energy-saving power configuration lowers long-term operational costs. With a service life of 15+ years for core equipment, the 300 TPH granite crushing system ensures quick investment return for medium to large-scale projects.

Project Features

Zhongyu Dingli's DLKPC Double-Cavity Hard Rock Crusher is applicable for the crushing and shaping of high-hardness materials including cobblestone, basalt and granite. Adopting a symmetrical double-cavity design, it can hold more materials at one time and realize high output. Its rotor is capable of forward and reverse rotation, and the hammer heads can be reversed for reuse — this effectively cuts down the costs of hammer head replacement and equipment maintenance. In terms of discharging, the gap between the hammer heads and impact liners can be precisely adjusted through the control system. The particle shape of the crushed finished products is superior to the specified standards for construction materials.
